Abstract
The invention discloses a method for automatically controlling a door lock of a washing machine. A reserve power supply, a door lock control circuit and a water level monitoring device are arranged in the washing machine, wherein the door lock control circuit is connected with the reserve power supply and used for controlling the door lock. After power failure, the water level of the washing machine is firstly monitored, the door lock is allowed to be unlocked by a user when the water level is low, and water in a washtub is prevented from overflowing due to mistaken unlocking of the door lock.
Description
Technical field
The present invention relates to the washing machine field, particularly the method for roller washing machine control door lock.
Background technology
The roller washing machine of prior art, when washing, if the user thinks to add clothing midway, owing to be in high water level in the bucket, door lock can't be opened, and some users can pull out plug, open door lock then, and this just causes overflowing of inner bucket water.If washing machine power down midway, the user may think that washing finishes, and opens behind the door and also can cause overflowing of inner bucket water.
Therefore, need a kind of new technical scheme to address the above problem.
Summary of the invention
To above-mentioned existing in prior technology problem and shortage, the purpose of this invention is to provide a kind of method that automatic control gate is locked when washing machine cuts off the power supply.
For realizing above-mentioned purpose, the method for washing machine automatic control gate lock of the present invention can adopt following technical scheme:
The method of a kind of washing machine automatic control gate lock is provided with stand-by power supply, is connected and is used to control door lock control circuit, the Level monitor of door lock with stand-by power supply in washing machine;
This method may further comprise the steps:
(1), when washing machine cuts off the power supply, use water level in the Level monitor monitoring washtub, if monitoring is high water level, then get into step (3), if monitoring is low water level, then get into step (2);
(2), door lock control circuit control door lock is freely opened;
(3), the locked door lock of door lock control circuit, alarm draining simultaneously, and whether point out the manual-lock stand-by power supply if select to close stand-by power supply, then gets into step (4), if select not close stand-by power supply, then gets into step (5);
(4), the locked releasing of door lock;
(5), get back to step (1) sensed water level again after the draining once more.
The present invention is compared with prior art: washing machine sensed water level at first after outage, and when low water level, just allow the user to open door lock, and whether manual-lock stand-by power supply option is provided, make the user when door lock is locked, still can select to open door lock.
Description of drawings
Fig. 1 is the flow chart of the method for washing machine automatic control gate lock of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment; Further illustrate the present invention; Should understand the following specific embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Please combine shown in Figure 1; The method of a kind of washing machine automatic control gate lock disclosed by the invention is characterized in that: stand-by power supply is set in washing machine, is connected and is used to control door lock control circuit, Level monitor, high water level indicator lamp and the low water level indicator lamp of door lock with stand-by power supply.
This method may further comprise the steps:
(1), when washing machine cuts off the power supply, use water level in the Level monitor monitoring washtub, if monitoring is high water level, then get into step (3); If monitoring then gets into step (2) for low water level, judge that the mode of water level height is; A water level standard value is set, detected water level and water level standard value are compared, if water level is higher than the water level standard value; Then be judged as high water level,, then be judged as low water level if water level is less than or equal to the water level standard value;
(2), the low water level indicator lamp opens, door lock control circuit control door lock is freely opened;
(3), the high water level indicator lamp is opened the locked door lock of door lock control circuit, alarm draining simultaneously; And whether point out the manual-lock stand-by power supply, if select to close stand-by power supply, then get into step (4); If select not close stand-by power supply, then get into step (5);
(4), the locked releasing of door lock;
(5), get back to step (1) sensed water level again after the draining once more.
Use the washing machine of this method, washing machine sensed water level at first just allows the user to open door lock when low water level after outage, opens door lock and causes the water in the washtub to overflow to prevent mistake.Whether manual-lock stand-by power supply option is provided simultaneously, makes the user when door lock is locked, still can select to open door lock.
